Magnetic tape cassette apparatus for reversible playing of magnetic tape cassettes

摘要

A magnetic tape cassette apparatus for reversible playing of magnetic tape cassettes with two tape spools and spool hubs, whereby one of the tape spools is rotatable in the playback or fast winding mode at any given moment. For the fast winding function, a transmission device is adjusted by insertable pushbutton rods for fast forward or fast rewind, respectively, so that the rotary movement of a drive gear for the fast forward direction can be transmitted to the one spool hub and for the fast rewind direction to the other spool hub. A selection plate is active between the pushbutton rods and the switching device and is brought into a position corresponding to the next previous tape direction, which position determines the assignment of the pushbutton rods. The selection plate derives its position responsible for the correct control of the pushbutton rods from an adjustment member which determines the playing direction by means of a position change. The pushbutton rods each cause the tape to fast wind in the same respective absolute direction irrespective of whether the apparatus was previously in the forward or reverse play mode.
